Best MTD Software for Self-Employed UK 2026 — Honest Comparison

What MTD Software Must Do (Legal Requirements)

HMRC's rules are specific. Your software must:

• Record income and expenses digitally (no paper records)
• Submit quarterly updates to HMRC (5 Jan, 5 May, 5 Aug, 5 Nov)
• Submit End of Period Statement (EOPS) after tax year ends
• Submit Final Declaration by 31 January
• Use digital links between different software (if you use multiple tools)

If your software can't do all five, it's not MTD-compliant. HMRC maintains an official list of approved software, but that list includes 200+ options (useless for decision-making).

Quick Comparison Table

Prices correct as of February 2026. CIS support means Construction Industry Scheme deductions can be recorded properly.

QuickBooks — Best for Beginners

Price: £15/month (Simple Start), £26/month (Essentials), £30/month (Plus)

Best for: First-time business owners who need something that "just works"

What It Does Well

• Dead simple setup — 10 minutes from signup to first invoice
• Automatic bank feeds from every UK bank
• Receipt capture via phone (snap a photo, done)
• Invoicing that clients understand (clean, professional)
• MTD submission built-in — no confusing export steps
• CIS support on Plus tier (£30/month)

What It Doesn't Do

• No project tracking (use Essentials tier or higher)
• Limited reporting compared to Xero
• Can feel "American" (talks about "sales tax" before switching to VAT)

Real Cost

£15/month if you're solo with simple needs. £26/month if you bill by project. £30/month if you're in construction (CIS required).

Verdict: If you've never used accounting software and just want to stop HMRC fining you, this is the safest choice.

Xero — Best for Growth

Price: £15/month (Early), £28/month (Growing), £38/month (Established)

Best for: Businesses planning to hire, scale, or add complexity

What It Does Well

• Unlimited users on all plans (QuickBooks charges per user)
• Best-in-class integrations (1,000+ apps connect to Xero)
• Multi-currency support (if you invoice internationally)
• Project tracking from Growing tier up
• Beautiful reporting — best dashboards of any platform

What It Doesn't Do

• No CIS support — construction subcontractors need a workaround
• Steeper learning curve than QuickBooks
• £15 tier only allows 20 invoices/quotes per month

Real Cost

£28/month realistically (Early tier is too limited for most). Add £10-20/month for apps (receipt scanning, time tracking, etc.).

Verdict: Choose Xero if you're growing fast or need integrations. Avoid if you're in construction (CIS gap is a dealbreaker).

FreeAgent — Best for Self-Assessment

Price: £19/month (solo), £29/month (partner/family business)

Best for: Sole traders who want Self-Assessment built in

What It Does Well

• Self-Assessment tax estimate built-in — always know what you owe
• Expense tracking via phone (best mobile app in this list)
• CIS support included
• Time tracking for freelancers
• Works with NatWest, RBS, Barclays, HSBC for free (bank partnerships = lower cost)

What It Doesn't Do

• Limited integrations compared to Xero
• Solo plan caps at 1 user (can't add a bookkeeper without upgrading)
• Not great for product-based businesses (designed for services)

Real Cost

£19/month if solo. Free if you bank with NatWest/RBS and qualify for their partnership deal.

Verdict: Best choice if you're a solo freelancer who wants tax estimates without hiring an accountant.

Sage — Legacy Option

Price: £12/month (Start), £27/month (Standard), £32/month (Plus)

Best for: People already using Sage who don't want to switch

What It Does Well

• Been around forever (your accountant probably knows it)
• CIS support on Standard and Plus
• Payroll included on Plus tier

What It Doesn't Do

• Interface feels dated (2015-era design)
• Mobile app is clunky
• Fewer integrations than Xero or QuickBooks

Real Cost

£27/month if you need CIS. £32/month if you have employees.

Verdict: Only choose this if you're already using Sage Desktop and your accountant insists. Otherwise, QuickBooks or FreeAgent are better.

Zoho Books — Cheapest

Price: £10/month (Standard), £20/month (Professional), £25/month (Premium)

Best for: Businesses that need cheap MTD compliance and nothing else

What It Does Well

• Cheapest MTD-compliant option
• Unlimited invoices on all plans
• Good if you already use Zoho CRM (integrates seamlessly)

What It Doesn't Do

• No CIS support
• Bank feeds are slow (2-3 day delay)
• Support is email-only (no phone)
• Interface feels like enterprise software (because it is)

Real Cost

£10/month if you have basic needs. £20/month if you need project tracking.

Verdict: Choose this if you're on a tight budget and don't need CIS. Otherwise, pay £5 more for QuickBooks (better UX).

Clear Books — UK-Focused

Price: £11/month (Micro), £18/month (Small), £29/month (Medium)

Best for: Businesses that want UK-specific features (VAT MOSS, reverse charge, etc.)

What It Does Well

• Built for UK tax rules (not adapted from US software)
• CIS support on all plans
• VAT complexity handled properly (MOSS, Flat Rate Scheme, margin schemes)

What It Doesn't Do

• Mobile app is basic
• Smaller ecosystem (fewer integrations)
• Less well-known (harder to find YouTube tutorials)

Real Cost

£11/month if micro (under 20 invoices/month). £18/month realistically.

Verdict: Good choice if you sell cross-border or have complex VAT (Amazon sellers, etc.). Otherwise, QuickBooks is easier.

KashFlow — Sage's Budget Brand

Price: £12/month (Start), £20/month (Standard)

Best for: Simple businesses that don't need bells and whistles

What It Does Well

• Simple, clean interface
• Good for service businesses
• Owned by Sage (stable, won't disappear)

What It Doesn't Do

• No CIS support
• Limited reporting
• Mobile app is barebones

Real Cost

£12/month if very small. £20/month if you need multi-user access.

Verdict: Fine if you're tiny and don't need CIS. But QuickBooks is £3 more and better in every way.

Crunch — Accountancy Bundle

Price: £39.50/month (Self Assessment), £89.50/month (Limited Company)

Best for: People who want software + accountant in one package

What It Does Well

• Accountant included (they file your tax return)
• MTD submissions done for you
• Good for limited companies (handles Corp Tax, PAYE, VAT)

What It Doesn't Do

• Expensive if you only need software
• CIS support is limited (ask before signing up)
• You're locked in (can't switch accountants easily)

Real Cost

£39.50/month = £474/year. A standalone accountant charges £300-500/year, and software is £15-20/month = £180-240/year. Total: £480-740/year separately.

Verdict: Worth it if you're a limited company and hate admin. Not worth it if you're sole trader (just use FreeAgent for £19/month and file your own return).

Software to Avoid

Spreadsheets (Excel, Google Sheets)

Why: Not MTD-compliant. You can't submit quarterly updates from a spreadsheet. HMRC will fine you.

Exception: You can use spreadsheets + bridging software (like GoSimple Tax, £10/month) but that's more hassle than just using proper software.

Free Software (Wave, etc.)

Why: Wave doesn't support MTD for Income Tax (it does MTD for VAT, different thing). Other free tools are US-focused and don't understand UK tax.

Accountant-Only Portals

Why: Some accountants give you access to their software (IRIS, TaxCalc, etc.) but you can't use it yourself. If your accountant goes on holiday, you miss a deadline. Bad idea.

How to Choose (Decision Tree)

Final Thoughts

The "best" MTD software depends on your situation:

• Beginners: QuickBooks (£15/month)
• Freelancers: FreeAgent (£19/month)
• Construction: QuickBooks Plus (£30/month) or FreeAgent (£19/month)
• Growth businesses: Xero (£28/month)
• Budget-conscious: Zoho Books (£10/month)
• Want accountant included: Crunch (£39.50/month)

Most important rule: Choose something and get it set up. The £400-£2,000 in MTD penalties from April onwards will cost more than a year of software.

The deadline is 6 April 2026. If you're reading this in March and haven't signed up yet, pick QuickBooks and do it today.
